Metal-in-metal localized surface plasmon resonance [PDF]

open access: yesNanotechnology, 2009
Anomalous strong resonances in silver and gold nanoporous thin films which conduct are found to arise from isolated metal nano-islands separated from the surrounding percolating metal network by a thin loop of insulator. This observed resonant optical response is modelled.

Plasmonic Nanostructure Biosensors: A Review

open access: yesSensors, 2023
Plasmonic nanostructure biosensors based on metal are a powerful tool in the biosensing field. Surface plasmon resonance (SPR) can be classified into localized surface plasmon resonance (LSPR) and propagating surface plasmon polariton (PSPP), based on ...

Gold nano-ripple structure with potential for bio molecular sensing applications

open access: yesSensing and Bio-Sensing Research, 2016
We introduce a simple and cost-effective scheme for bio-sensing using nano-ripple structures. One dimensional metallic nano-ripple structures formed by gas cluster ion beam irradiation have shown polarization of light as well as localized surface plasmon

Au-Graphene Hybrid Plasmonic Nanostructure Sensor Based on Intensity Shift

open access: yesSensors, 2017
Integrating plasmonic materials, like gold with a two-dimensional material (e.g., graphene) enhances the light-material interaction and, hence, plasmonic properties of the metallic nanostructure.
